Description

Technical Field

[0001] This utility model relates to the field of microbial detection equipment technology, and more specifically, to a swab tester applicable to multiple scenarios. Background Technology

[0002] In fields such as microbiology, food science, biomedical engineering, and environmental science, the detection and control of microbial contamination are crucial. Traditional microbial wiping tests largely rely on manual operation, such as manually wiping the sample surface with cotton swabs or specific tools, followed by microbial culture and counting to assess cleaning effectiveness. For example, existing technology, such as Chinese utility model patent (CN 109749927 A), involves fixing the swab to a platform assembly and then moving a sliding component to detect the wiping effect. However, this method has many drawbacks, such as being cumbersome, time-consuming, labor-intensive, and susceptible to human error leading to unstable test results.

[0003] Specifically, during manual wiping, it is difficult to maintain consistent control over wiping force, speed, direction, and number of wipes, thus introducing testing errors. Furthermore, prolonged repetitive work can easily lead to operator fatigue, further increasing the variability of test results. Moreover, for large-scale or high-frequency microbial testing needs, manual methods are clearly insufficient to meet the requirements of efficient and accurate testing.

[0004] With the rapid development of automation technology, automated wiping testers applicable to multiple scenarios have emerged to address the aforementioned issues. While existing automated testers on the market have achieved automation to some extent, they still suffer from problems such as complex structure, inconvenient operation, and insufficient precision control. For example, some devices lack precise movement control mechanisms, failing to ensure a constant relative position between the wiping head and the sample surface during the wiping process, thus affecting the accuracy and repeatability of the test.

[0033] The present invention will be further described below through specific embodiments.

[0034] Example

[0035] This embodiment provides a wiping tester applicable to multiple scenarios, such as... Figure 1 As shown, it includes an operating table 10, a horizontal moving mechanism 20, and a vertical moving mechanism 30;

[0036] The horizontal moving mechanism 20 is mounted on the operating table 10, and the vertical moving mechanism 30 is mounted on the operating table 10 via the mounting bracket 40;

[0037] The horizontal moving mechanism 20 includes a first power device 21, a first transmission component 22, and a carrying structure 23. The carrying structure 23 and the power device are slidably connected through the transmission component.

[0038] The carrier structure 23 includes a first guide sleeve 231, a wiping groove plate 232, and a carrier 233. The wiping groove plate 232 is fixedly connected to the first guide sleeve 231, and the carrier 233 can be fixedly placed on the wiping groove plate 232.

[0039] The first transmission assembly 22 includes a first frame 221, a first threaded rod 222, and a first guide rod 223. The first threaded rod 222 is rotatably connected to the first frame 221, and the first guide rod 223 is fixedly connected to the first frame 221. The first power device 21 is mounted on the frame and is transmittably connected to the first threaded rod 222.

[0040] The first guide sleeve 231 is provided with a guide hole 2311 and a threaded hole 2312. The guide hole 2311 is sleeved with the first guide rod 223, and the threaded hole 2312 is threadedly connected to the first threaded rod 222.

[0041] The horizontal moving mechanism 20 works as follows: the power device is activated to provide power for the rotation of the first threaded rod 222. The first threaded rod 222 is threadedly connected to the threaded hole 2312. The rotation of the first threaded rod 222 causes the first guide sleeve 231 to move. Because the first guide sleeve 231 is sleeved on the first guide rod 223, it will move along the horizontal direction of the first guide rod 223, thereby driving the wiping groove plate 232 and the carrier 233 to move. In actual use, the carrier 233 is coated with microorganisms, waiting to be wiped.

[0042] Specifically, the wiping groove plate 232 is provided with a placement groove 2321, and the carrier 233 is fitted into the placement groove 2321.

[0043] Specifically, such as Figure 2 As shown, the edge of the placement groove 2321 is provided with a groove 2322 to facilitate the removal of the carrier 233 and make it easier to put the carrier 233 in and take it out.

[0044] Specifically, the carrier 233 is configured as a rectangular structure, and correspondingly, the placement groove 2321 is configured as a rectangular structure.

[0045] Specifically, the first power device 21 is configured as a first stepper motor, the first stepper motor is provided with an output shaft, and the output shaft is connected to the first threaded rod 222.

[0046] Specifically, the first bracket 221 includes an end plate 2211, on which a bearing hole 2212 is provided, and the first threaded rod 222 is sleeved with the bearing hole 2212.

[0047] Specifically, the first guide rod 223 is fixedly connected to the end plate 2211.

[0048] In this utility model, the vertical moving mechanism 30 includes a second power device 31, a second transmission component 32, and a wiping structure 33. The wiping structure 33 and the second power device 31 are slidably connected through the second transmission component 32.

[0049] Specifically, the second power device 31 can also be configured as a stepper motor.

[0050] Specifically, the second transmission assembly 32 includes a second bracket 321, a second threaded rod 322, and a second guide rod 323. The second threaded rod 322 is transmissively connected to the second power device 31 and rotatably connected to the second bracket 321. The second guide rod 323 is fixedly installed on the second bracket 321.

[0051] like Figure 3As shown, the wiping structure 33 includes a mounting base 331 and a wiping head 332. The wiping head 332 is mounted on the mounting base 331. The mounting base 331 is threadedly connected to the second threaded rod 322. The mounting base 331 is sleeved with the second guide rod 323.

[0052] The vertical moving mechanism 30 operates as follows: the second power device 31 is activated, driving the second threaded rod 322 to rotate. The second threaded rod 322 is threadedly connected to the mounting base 331, and the mounting base 331 is sleeved with the second guide rod 323, allowing the mounting base 331 to slide unidirectionally upward along the second guide rod 323. The movement of the mounting base 331 drives the wiping head 332 to move unidirectionally upward together. When the wiping head 332 is raised above the carrier 233, the second power device 31 is turned off, the second threaded rod 322 is in a free state, and the wiping head 332 falls freely under the action of gravity until it presses on the carrier 233.

[0053] The overall process of the wiping test involves the cooperation of the horizontal moving mechanism 20 and the vertical moving mechanism 30: First, the carrier 233 coated with microorganisms in the horizontal moving mechanism 20 moves horizontally to a position below the wiping head 332; then, the wiping head 332 in the vertical moving mechanism 30 falls freely downwards until it comes into contact with the carrier 233; afterwards, the horizontal moving mechanism 20 drives the carrier 233 to move horizontally in the opposite direction, completing the wiping work of the wiping head 332 on the surface of the carrier 233.

[0054] The entire process requires no human intervention, and during repeated wiping, the relative position of the wiping head 332 and the carrier 233 remains fixed each time. The distance and speed of the horizontal reciprocating motion of the carrier 233 are controllable, ensuring the consistency of the wiping test conditions, avoiding test errors caused by manual operation, and making the test results more reliable, stable and accurate.

[0055] Specifically, the wiping head 332 is configured as a rectangular structure.

[0056] Specifically, the mounting base 331 includes a second guide sleeve, which has a guide hole 2311 and a threaded hole 2312.

[0057] Specifically, the mounting bracket 40 includes two symmetrically arranged bracket plates 41, which are mounted on the operating table 10.

[0058] Specifically, the control panel 10 is equipped with a human-machine interface 11.

[0059] Specifically, the operating console 10 is equipped with a timing module and a counting module. The timing module and the counting module are electrically connected to the first power unit 21, the second power unit 31, and the human-machine interface 11, respectively. The timing module and the counting module are also electrically connected to the PLC control system. The timing module is used to record the rotational speed of the power unit, and the counting module is used to record the number of forward and reverse starts of the power unit. The PLC control system works with the human-machine interface 11 to set parameters for time and number of starts. The human-machine interface 11 can also display the operating status of the device.

[0060] It should be noted that the timing module, counting module, and PLC control system are all conventional technologies. This application does not improve the internal structure of these electronic components and only uses them for general purposes.

[0061] Specifically, the wiping head is made of 304 stainless steel; the wiping groove plate is made of acrylic.

[0062] Specifically, the wiping head has a certain weight to ensure a fixed wiping pressure.

[0063] This utility model has been described through embodiments, but it does not constitute a limitation on this utility model. Other variations of the disclosed embodiments, which are readily apparent to those skilled in the art, should fall within the scope of the claims of this utility model, with reference to the description of this utility model.
